on a new build you install the os first. on the os reboot have a usb stick that has the newest intel chipset drivers if it an intel mb or amd chipset. you can use the drivers on the mb cd if you have to but most times there 5-6 months old. install the mb chipset drivers first then reboot. then on the mb driver cd install the audio and network drivers. most audio drivers from realtek will have you reboot and it install it self on the reboot. after the network drivers are install go to nvidia or ati web page and let the drivers auto scan your system and install the newest driver.
